Given:-

  • AB is a segment, the point P is the perpendicular bisector of segment AB.
  • The length of the AP exceeds the length of AB by 7cm.
  • The perimeter of ∆ABP is 38cm.

Find:-

Sides of the ABP.

Assume:-

That perpendicular P lies on the segment AB at point C.

Solution:-

[ Refer the attachment for the figure. ]

AP exceeds the length AB by 7 cm.

According to question and figure -

  • AP = BP = y
  • AB = x
  • AC = CB = x/2

According to the question,

→ y = x + 7 ....(1)

Also, given that the perimeter of the triangle is 38 cm.

\sf{Perimeter\:of\:\triangle\:ABP\:=\:38\:cm}

The perimeter of the triangle is the sum of it's all sides.

i.e.

→ y + y + x = 38

→ 2y + x = 38

→ 2(x + 7) + x = 38 [From (1)]

→ 2x + 14 + x = 38

→ 3x = 24

→ x = 8

Substitute value of x = 8 in (eq 1)

→ y = 8 + 7

→ y = 15

As -

  • AP = BP = y
  • AB = x

So,

→ AP = BP = 15 cm

→ AB = 8 cm

•°• Sides of the triangle are 8cm, 15cm and 15cm
